Abstract
A method and system for detecting the presence of an occupant on a vehicle seat is disclosed. The vehicle seat is provided with at least a pair of electrodes which are connected to a detection circuit for detecting a change in capacitance between the electrodes. If the detection circuit detects a sufficiently large change in capacitance, a positive detection signal is produced. To reduce the risk of interference, the electrodes of the detection circuit are substantially insulated from the chassis of the vehicle and its electrical system when the detection circuit is in an active condition.
